Matrix doesnot has value. Determinant only has value
Bright Parrot
On Question 1 (if its not shuffled) it says :

Matrix has a value
A.True
B.False
C.Depends on matrix
D. None of above

Your answer is false :

but from source https://en.wikipedia.org/wiki/Matrix_(mathematics) Matrix is defined as :

A symmetric n×n-matrix A is called positive-definite if the associated quadratic form
f (x) = xTA x
has a positive value for every nonzero vector x in Rn. If f (x) only yields negative values then A is negative-definite; if f does produce both negative and positive values then A is indefinite.

Doesn't this clash?


Thank you and i appreciated your word Good luck.

Positive Definite is something different.
